repo-settings: read an int for index.version
Several config options were combined into a repo_settings struct in
ds/feature-macros, including a move of the "index.version" config
setting in 7211b9e (repo-settings: consolidate some config settings,

clearly a factor of copy-paste overload, the config setting is parsed
with repo_config_ge_bool() instead of repo_config_get_int(). This means
that a setting "index.version=4" would not register correctly and would
revert to the default version of 3.
I caught this while incorporating v2.24.0-rc0 into the VFS for Git
codebase, where we really care that the index is in version 4.
This was not caught by the codebase because the version checks placed
in t1600-index.sh did not test the "basic" scenario enough. Here, we
modify the test to include these normal settings to not be overridden by
features.manyFiles or GIT_INDEX_VERSION. While the "default" version is
3, this is demoted to version 2 in do_write_index() when not necessary.

ci: fix GCC install in the Travis CI GCC OSX job

Error: caskroom/cask was moved. Tap homebrew/cask-cask instead.
So let's try to call `brew cask install perforce` first (which is what
that error message suggests, in a most round-about way).
Prior to 672f51cb we used to install the 'perforce' package with 'brew
install perforce' (note: no 'cask' in there). The justification for 672f51cb was that the command 'brew install perforce' simply stopped
working, after Homebrew folks decided that it's better to move the
'perforce' package to a "cask". Their justification for this move was
that 'brew install perforce' "can fail due to a checksum mismatch ...",
and casks can be installed without checksum verification. And indeed,
both 'brew cask install perforce' and 'brew install
caskroom/cask/perforce' printed something along the lines of:
==> No checksum defined for Cask perforce, skipping verification
It is unclear why 672f51cb used 'brew install caskroom/cask/perforce'
instead of 'brew cask install perforce'. It appears (by running both
commands on old Travis CI macOS images) that both commands worked all
the same already back then.
In any case, as the error message at the top of this commit message
shows, 'brew install caskroom/cask/perforce' has stopped working
recently, but 'brew cask install perforce' still does, so let's use
that.
CI servers are typically fresh virtual machines, but not always. To
accommodate for that, let's try harder if `brew cask install perforce`
fails, by specifically pulling the latest `master` of the
`homebrew-cask` repository.
This will still fail, of course, when `homebrew-cask` falls behind
Perforce's release schedule. But once it is updated, we can now simply
re-run the failed jobs and they will pick up that update.
As for updating `homebrew-cask`: the beginnings of automating this in
https://dev.azure.com/gitgitgadget/git/_build?definitionId=11&_a=summary
will be finished once the next Perforce upgrade comes around.

ci(visual-studio): actually run the tests in parallel
Originally, the CI/PR builds that build and test using Visual Studio
were implemented imitating `linux-clang`, i.e. still using the

Later (but still before the patches made their way into git.git's
`master`), however, this was changed to generate Visual Studio project
files and build the binaries using `MSBuild`, as this reflects more
accurately how Visual Studio users would want to build Git (internally,
Visual Studio uses `MSBuild`, or at least something very similar).
During that transition, we needed to implement a new way to run the test
suite in parallel, as Visual Studio users typically will only have a Git
Bash available (which does not ship with `make` nor with support for
`prove`): we simply implemented a new test helper to run the test suite.
This helper even knows how to run the tests in parallel, but due to a
mistake on this developer's part, it was never turned on in the CI/PR
builds. This results in 2x-3x longer run times of the test phase.

94da9193a6 (grep: add support for PCRE v2, 2017-06-01) didn't include
a way to override the system allocator, and so it is incompatible with
custom allocators (e.g. nedmalloc). This problem became obvious when we
tried to plug a memory leak by `free()`ing a data structure allocated by
PCRE2, triggering a segfault in Windows (where we use nedmalloc by
default).
PCRE2 requires the use of a general context to override the allocator
and therefore, there is a lot more code needed than in PCRE1, including
a couple of wrapper functions.
Extend the grep API with a "destructor" that could be called to cleanup
any objects that were created and used globally.
Update `builtin/grep.c` to use that new API, but any other future users
should make sure to have matching `grep_init()`/`grep_destroy()` calls
if they are using the pattern matching functionality.
Move some of the logic that was before done per thread (in the workers)
into an earlier phase to avoid degrading performance, but as the use of
PCRE2 with custom allocators is better understood it is expected more of
its functions will be instructed to use the custom allocator as well as
was done in the original code[1] this work was based on.

Note that nedmalloc, as well as other custom allocators like jemalloc
and mi-malloc, can be configured at runtime (via `LD_PRELOAD`),
therefore we cannot know at compile time whether a custom allocator is
used or not.
Make the minimum change possible to ensure this combination is supported
by extending `grep_init()` to set the PCRE1 specific functions to Git's
idea of `malloc()` and `free()` and therefore making sure all
allocations are done inside PCRE1 with the same allocator than the rest
of Git.
This change has negligible performance impact: PCRE needs to allocate
memory once per program run for the character table and for each pattern
compilation. These are both rare events compared to matching patterns
against lines. Actual measurements[2] show that the impact is lost in

remote-curl: pass on atomic capability to remote side
When pushing more than one reference with the --atomic option, the
server is supposed to perform a single atomic transaction to update the
references, leaving them either all to succeed or all to fail. This
works fine when pushing locally or over SSH, but when pushing over HTTP,
we fail to pass the atomic capability to the remote side. In fact, we
have not reported this capability to any remote helpers during the life
of the feature.
Now normally, things happen to work nevertheless, since we actually
check for most types of failures, such as non-fast-forward updates, on
the client side, and just abort the entire attempt. However, if the
server side reports a problem, such as the inability to lock a ref, the
transaction isn't atomic, because we haven't passed the appropriate
capability over and the remote side has no way of knowing that we wanted
atomic behavior.
Fix this by passing the option from the transport code through to remote
helpers, and from the HTTP remote helper down to send-pack. With this
change, we can detect if the server side rejects the push and report
back appropriately. Note the difference in the messages: the remote
side reports "atomic transaction failed", while our own checking rejects
pushes with the message "atomic push failed".
Document the atomic option in the remote helper documentation, so other

fetch-pack: write fetched refs to .promisor
The specification of promisor packfiles (in partial-clone.txt) states
that the .promisor files that accompany packfiles do not matter (just
like .keep files), so whenever a packfile is fetched from the promisor
remote, Git has been writing empty .promisor files. But these files
could contain more useful information.
So instead of writing empty files, write the refs fetched to these
files. This makes it easier to debug issues with partial clones, as we
can identify what refs (and their associated hashes) were fetched at the
time the packfile was downloaded, and if necessary, compare those hashes
against what the promisor remote reports now.
This is implemented by teaching fetch-pack to write its own non-empty
.promisor file whenever it knows the name of the pack's lockfile. This
covers the case wherein the user runs "git fetch" with an internal
protocol or HTTP protocol v2 (fetch_refs_via_pack() in transport.c sets
lock_pack) and with HTTP protocol v0/v1 (fetch_git() in remote-curl.c
passes "--lock-pack" to "fetch-pack").

remote-curl: use argv_array in parse_push()
Use argv_array to build an array of strings instead of open-coding it.
This simplifies the code a bit.
We also need to make the specs parameter of push(), push_dav() and

fine, as all three only actually read from the specs array anyway.

column: use utf8_strnwidth() to strip out ANSI color escapes
Make use of utf8_strnwidth()'s feature to skip ANSI escape sequences
instead of open-coding it. This shortens the code and makes it more
consistent.
This changes the behavior, though: The old code skips all kinds of
Control Sequence Introducer sequences, while utf8_strnwidth() only skips
the Select Graphic Rendition kind, i.e. those ending with "m". They are
used for specifying color and font attributes like boldness. The only
other kind of escape sequence we print in Git is Erase in Line, ending
with "K". That's not used for columnar output, so this difference
actually doesn't matter here.

http-push: simplify deleting a list item
The first step for deleting an item from a linked list is to locate the
item preceding it. Be more careful in release_request() and handle an
empty list. This only has consequences for invalid delete requests
(removing the same item twice, or deleting an item that was never added
to the list), but simplifies the loop condition as well as the check
after the loop.
Once we found the item's predecessor in the list, update its next
pointer to skip over the item, which removes it from the list. In other
words: Make the item's successor the successor of its predecessor.
(At this point entry->next == request and prev->next == lock,
respectively.) This is a bit simpler and saves a pointer dereference.

stash: avoid recursive hard reset on submodules
git stash push does not recursively stash submodules, but if
submodule.recurse is set, it may recursively reset --hard them. Having
only the destructive action recurse is likely to be surprising
behaviour, and unlikely to be desirable, so the easiest fix should be to
ensure that the call to git reset --hard never recurses into submodules.

documentation: add tutorial for object walking
Existing documentation on object walks seems to be primarily intended
as a reference for those already familiar with the procedure. This
tutorial attempts to give an entry-level guide to a couple of bare-bones
object walks so that new Git contributors can learn the concepts
without having to wade through options parsing or special casing.
The target audience is a Git contributor who is just getting started
with the concept of object walking. The goal is to prepare this
contributor to be able to understand and modify existing commands which
perform revision walks more easily, although it will also prepare
contributors to create new commands which perform walks.
The tutorial covers a basic overview of the structs involved during
object walk, setting up a basic commit walk, setting up a basic
all-object walk, and adding some configuration changes to both walk
types. It intentionally does not cover how to create new commands or
search for options from the command line or gitconfigs.
There is an associated patchset at
https://github.com/nasamuffin/git/tree/revwalk that contains a reference
implementation of the code generated by this tutorial.

fsmonitor: don't fill bitmap with entries to be removed
While doing some testing with fsmonitor enabled I found
that git commands would segfault after staging and
unstaging an untracked file. Looking at the crash it
appeared that fsmonitor_ewah_callback was attempting to
adjust bits beyond the bounds of the index cache.
Digging into how this could happen it became clear that
the fsmonitor extension must have been written with
more bits than there were entries in the index. The
root cause ended up being that fill_fsmonitor_bitmap was
populating fsmonitor_dirty with bits for all entries in
the index, even those that had been marked for removal.
To solve this problem fill_fsmonitor_bitmap has been
updated to skip entries with the the CE_REMOVE flag set.
With this change the bits written for the fsmonitor
extension will be consistent with the index entries
written by do_write_index. Additionally, BUG checks
have been added to detect if the number of bits in
fsmonitor_dirty should ever exceed the number of
entries in the index again.
Another option that was considered was moving the call
to fill_fsmonitor_bitmap closer to where the index is
written (and where the fsmonitor extension itself is
written). However, that did not work as the
fsmonitor_dirty bitmap must be filled before the index
is split during writing.

In the case where one wants to inspect the output hidden by
